The Best Time to Visit Every Region of Mexico

Mexico spans 31 states, 3 time zones, and climates ranging from alpine to tropical desert to Caribbean. Telling someone "the best time to visit Mexico is November through April" is like telling someone "the best time to visit the United States is spring." It's not wrong, but it's not useful either.

Here's a region-by-region breakdown of when to go, what to expect, and when to avoid.

Yucatan Peninsula and the Riviera Maya

Best months: November through April.

The dry season on the Yucatan runs from roughly November through April, with low humidity, warm days (28-32°C / 82-90°F), and cool evenings. This is peak tourist season, which means higher hotel prices and crowded archaeological sites, but the weather justifies it.

The rainy season (May through October) brings afternoon downpours that are heavy but usually short. Mornings are often sunny. Humidity climbs noticeably in July and August. Most travelers find the rain manageable, and prices drop 30-40% across the region.

Hurricane season runs June through November, with the highest risk in September and early October. Cancun, Playa del Carmen, and Tulum are all in the hurricane corridor. Major storms don't hit every year, but when they do, they're serious. Travel insurance with cancellation coverage is worth it if you're booking during these months.

Sweet spot: Late November or early December. Dry season has started, hurricane risk is essentially gone, and the holiday rush hasn't kicked in yet. Prices are still shoulder-season level.

Avoid: The last 2 weeks of December and Easter week ("Semana Santa"). Prices spike, beaches are packed, and availability at popular restaurants and tours dries up. If those are your only options, book 3-4 months in advance.

Mexico City

Best months: March through May, October through November.

CDMX sits at 2,240 meters (7,350 feet) in a high valley, which gives it a mild climate year-round that doesn't track with what people expect from Mexico. Average highs hover around 22-26°C (72-79°F) in every month. You'll want a light jacket at night. It never gets tropical-hot.

The rainy season (June through September) brings daily afternoon thunderstorms that can be intense but rarely last more than an hour. Mornings are usually clear. The rain keeps the city green and washes the air clean, which matters in a city that sometimes struggles with smog. Some travelers actually prefer CDMX in the rainy season because the morning light is better and the parks are lush.

March through May is warm and dry with jacaranda trees in full bloom across the city (late March through mid-April is peak). The purple canopies across Roma, Condesa, and Coyoacan are one of the most photographed things in Mexico.

Sweet spot: Late March. Jacarandas are blooming, the weather is perfect, and you're between the Semana Santa crowds and the summer rainy season.

Avoid: Late December through early January if you want the city's full energy. Many restaurants close for the holidays, and the city empties as residents leave for vacation. If you want a quiet CDMX, that's actually a pro.

Pacific Coast (Puerto Vallarta, Riviera Nayarit, Sayulita)

Best months: November through May.

The Pacific coast of Mexico has a more defined dry season than the Caribbean side. From November through May, you can expect clear skies, low humidity, warm water (26-28°C / 79-82°F), and air temperatures in the high 20s to low 30s (°C). This is prime season for the Banderas Bay area.

Whale watching season runs December through March. Humpback whales migrate to the warm waters of Banderas Bay to breed and calve. Boat tours run daily from Puerto Vallarta, Sayulita, and Punta Mita. If seeing humpbacks is on your list, January and February are the peak months.

The rainy season (June through October) is more pronounced here than on the Caribbean coast. June and July bring scattered afternoon storms. August and September can have sustained multi-day rain events, especially during hurricane season. October is the transition month: still humid, but storms become less frequent.

Water temperature stays warm year-round (never below 24°C / 75°F), which means swimming and snorkeling work in every month.

Sweet spot: Late January through February. Whale season is at its peak, the weather is flawless, and the post-holiday prices have settled. Late November is also excellent if you want to beat the winter rush.

Avoid: September. It's the wettest month, the most humid, and the highest hurricane risk on the Pacific. Many smaller restaurants and tour operators in Sayulita and San Pancho close for a few weeks during this period.

Oaxaca (City and Coast)

Best months: October through April (city), November through May (coast).

Oaxaca operates on two slightly different calendars depending on whether you're in the highland valleys (Oaxaca City, Monte Alban, the Zapotec villages) or the coast (Puerto Escondido, Huatulco, Mazunte).

Oaxaca City sits at 1,550 meters (5,085 feet), which keeps temperatures mild and pleasant year-round. The dry season (October through April) is ideal. Days are warm, nights are cool, and the sky is clear. The rainy season (May through September) brings afternoon storms similar to CDMX.

The Oaxaca coast is tropical and hot. Dry season runs November through May, with temperatures consistently in the 30s (°C) and water warm enough to skip a wetsuit. The surf season at Puerto Escondido peaks from April through October (bigger swells come from the south), which overlaps with the rainy season. Serious surfers time their trips for May through August. Everyone else should aim for November through March.

Day of the Dead (late October through November 2) is the single biggest cultural event in Oaxaca. If you want to experience it, book 6+ months in advance. Hotels in Oaxaca City sell out entirely for the last week of October. Prices triple. It's worth the premium if the celebration matters to you, but know what you're getting into.

Sweet spot: Late October (combining Day of the Dead with the start of dry season) or February (dry, uncrowded, everything open).

Avoid: July and August in the city if you dislike rain. The coast is fine year-round if you're a surfer; otherwise, steer toward the dry months.

Baja California Sur (Los Cabos, La Paz, Loreto)

Best months: October through May.

Baja is desert, which means the climate rules are different from the rest of Mexico. Rain is rare in any month (La Paz averages 6 inches of rain per year). The main variable is heat.

October through May is the comfortable window. Temperatures in Los Cabos range from the mid-20s to low 30s (°C), the water is warm enough for swimming, and the skies are reliably clear. Winter months (December through February) can see cooler evenings (15-18°C / 59-64°F) that feel refreshing after the summer heat.

June through September gets genuinely hot. Cabo San Lucas regularly hits 38°C (100°F) in August, and the humidity creeps up as tropical moisture moves in. September is hurricane season for Baja (Hurricane Odile in 2014 was a reminder that Cabo is not immune).

Whale watching in Baja is a separate calendar. Gray whales migrate to the lagoons on the Pacific side (Guerrero Negro, San Ignacio, Magdalena Bay) from January through March. These are the only places in the world where gray whales actively approach boats, and the experience is extraordinary. If whale watching is the priority, plan around late January through early March.

Sweet spot: November. Summer heat has broken, winter crowds haven't arrived, and water temperature is at its warmest from the summer heating (28°C / 82°F). Prices are shoulder-season.

Avoid: August and September for heat and hurricane risk.

Chiapas and the South

Best months: November through April.

Chiapas is lush, mountainous, and distinctly different from every other region on this list. San Cristobal de las Casas sits at 2,200 meters (7,200 feet) and can get cold at night (below 10°C / 50°F in December and January). Pack layers.

The dry season (November through April) is the clear winner. Clear skies for hiking, comfortable temperatures for exploring the colonial streets of San Cristobal, and low water levels that make the turquoise color of Agua Azul and the Sumidero Canyon more vivid.

The rainy season (May through October) is heavy. Chiapas is one of the wettest states in Mexico, and the rains here aren't quick afternoon showers. Multi-day wet periods are common, roads can flood, and some waterfalls become inaccessible or too turbid to enjoy.

Sweet spot: Late November. Rains have stopped, greenery is at its peak, and the tourist season hasn't fully begun.

Avoid: June through September if your plans involve waterfalls, jungle hikes, or the Lacandon rainforest. Road conditions deteriorate, and some attractions close.
